An Eye Doctor Explains the Everyday Habits Hurting Your Eyes

Ophthalmologist and eye surgeon Dr. Dagny Zhu breaks down what screen time is really doing to your eyes — from digital eye strain and dry eyes to myopia, headaches, blue light and changes in vision after 40.

In this episode of Live + Well, Dr. Zhu joins Melissa Magsaysay to separate eye health fact from hype. She explains the 20-20-20 rule for screen breaks, why she tells patients not to rub their eyes, whether blue light glasses and eye supplements actually work, and what you should know about reading glasses, LASIK and popular eye drops.

She also weighs in on viral eye color change surgery and explains why some redness-relief drops can actually make red eyes worse. And one of the biggest misconceptions about eye health? Having 20/20 vision doesn't necessarily mean your eyes are healthy. Dr. Zhu explains how routine eye exams can sometimes uncover serious conditions before you notice changes in your vision.
